Cool Brodie, thanks for the image and lengthy post!
Reading through your comments it makes total sense to do just that; prepare in CAD for as long as you can to make SU workflow less lengthy. The CAD files I received were actually a 3D terrain of the design levels of the site so I had actual finished surface to play with. the trouble was with the 2D file really; just as you said lines not joining, and small line segments and some slightly off Z made making faces a challenge and dropping linework over the terrain a time consuming task.....
Anyhow, I've learnt a lot to date so the next time I'm sure I'll get it done a whole lot quicker!!!
Ya, fixing things in CAD is crucial to not driving yourself mad. To deal with the Z axis thing you should definitely select all your linework in CAD and go to properties. If your linework is polylines you can just go to Elevation and set it to 0. If the linework is in regular lines then same deal except you have to set it to 0 in both the Start Z and End Z boxes.
Smustard.com has a lot of rubies that should help out a ton with this little areas where segments aren't quite attached or there are stray lines, etc. They cost a bit of money though and I'm cheap so I don't have them
That stray lines issue is huge by the way. For some reason if you have a stray little line inside of closed linework that would normally create a face, that stray line prevents SU from creating a face so you have to find the little bugger and delete it (or use a ruby to do that).
